Truck and shovel

Task masters


TruckLogic is a truck operator training curriculum developed by Vista Training, Inc., integrating computer-based training modules, PC-based simulation and structured on-the-job training. In a pilot program at Suncor’s oil sands mine in 2011, using TruckLogic resulted in a 50 per cent reduction in incidents and a 4.5 per cent increase in productivity. “TruckLogic is a blended learning approach,” says Chuck Frey, Vista Training’s marketing manager. “Instead of stuffing people’s heads full of information, we break it into chunks, based on tasks. We still have computer-based training for each task, but that’s immediately followed up by a PC simulation exercise for the same task, and then in the field, and that helps cement the learned knowledge because they’re learning and doing.”

Ready for the big leagues


There’s a new AC-drive P&H shovel on deck. As with its DC counterpart, the AC 4100XPC provides a 104-tonne nominal payload capacity specifically designed for high-production loading of 218-tonne to 363-tonne haul trucks and larger. It has a rugged, reliable and easy to maintain twin-leg dipper handle design combined with rack-and-pinion crowd to obtain high dipper fill factors in difficult digging conditions. And its control system and maintenance-friendly modular design are geared for making the P&H 4100XPC easy to troubleshoot and maintain. “The latest 4100XPC AC shovels are achieving some of the highest productivity and availability metrics in the mining industry,” says Steve Droste, manager of sales and marketing, Joy Global Canada.

Power and agility


Hitachi’s new EX2600-6 excavator has Tier-2 engine technology from Cummins that lowers operating costs, increases production and improves reliability. Available in BE backhoe or front shovel configurations, the new model has a seven per cent increase in engine horsepower and up to a 10 per cent increase in hydraulic output over its predecessor. Combined with a redesigned, shorter reach backhoe front, bucket capacity on the backhoe has been increased. “For the shovel front, the increase in performance is due to a reduction in cycle times,” says Brian Mace, manager of mining product marketing and applications at Hitachi Construction & Mining Products. “Advancements in the latest models have incorporated satellite communication devices delivering a summary of machine performance and health to the customer, dealer and Hitachi to assist in monitoring the performance of the machine 24 hours per day.”


Go with the current


“In general, mine owners and operators are migrating to AC systems as they are more energy-efficient and utilize less mechanical parts, requiring less personal care and maintenance,” says Nimesh Sharan, GE’s senior product manager for motors. Accordingly, GE launched its new AC Excavator Solution in March 2012. It is a complete electric-drive solution, which includes a family of AC motors, drives, controls, engineering and field services that can be applied by owners of heavy equipment, earth-moving equipment and original equipment manufacturers to their draglines, shovels and blast-hole drills. “Mining companies are increasingly under pressure to find more energy efficient and reliable solutions,” Sharan says. “Our end-to-end solution offering is truly unique in the industry and includes up-front application engineering, rugged, field-tested equipment and field engineering support for installations.”


Leading lines


Made of aramid fibre, FibreMax's customized pendant lines for shovels are an alternative to steel lines and weigh 90 per cent less. Wilco van Zonneveld, the company’s business development manager, argues they are the better choice. “[Our lines] have been tested for more than two million load cycles without any loss or damage and outperform steel lines by far with a service life that is 15 times that of steel,” Available in any break load and with lengths of up to 140 metres, they are also maintenance-free and are made to exact lengths. The option of an integrated optic fibre provides real-time information and ready-to-use data on the lines’ service life and need for maintenance.


Plate is great


South Africa-based Van Reenen Steel (Pty) Ltd. designs, manufactures, and repairs loading tools and truck bodies using steel plate. As part of the repair business, the company passes on issues identified with frequent repairs to its design engineering department. All of that data collection helped design the innovative VR Truck Body, which in 2010 earned Van Reenen Steel the prestigious Swedish Steel Prize for design innovation. “The VR Truck Body has rounded corners, which allow dirt to discharge quickly,” says John van Reenen, the company’s managing director. “The ridge running down the middle of the body allows for better distribution of loads. It has a strong top rail, and lacks liners, since the floor and side plates are made from SSAB’s HARDOX abrasive resistant steel plate.”
